GOAL STOVE.

JAMES S. MARSH, OF LEWISBURGH, PENNSYLVANIA. Letters Patent No, 59,775,dated November 20, 18 66.

sPEoiFIcATIoN- TO ALL WHOM IT MAY CONCERN:

Beit known that I, JAMES S. MARSII, of Lewisburgh, in the county ofUnion, and State of Pennsylvania, have invented a new and improvedStove; and I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, making a part of this specification, in which-- Figure 1 is anelevation of one side of the improved stove.

Figure 2 is a vertical central section through the stove and its pipes.

Figure 3 is a horizontal section through the stove, taken in the planeindicated by the dotted line y y.

Figure 4 is a section through the stovetaken in the horizontal planeindicated by dotted line mm, fig. 2.

Figures 5, 6, 7, and 8, are views of a'stove which is a modification ofthat shown in fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates particularly to an improvement on that class ofstoves which are chiefly constructed of sheet metal, and commonly termeddrum stoves, but my invention is also applicable to many varieties ofstoves for burning either wood or coal. i

The nature of my invention consists in a stove which isconstructed withan upper single wall for radiating heat into the room in which the stoveis placed, a lower double wall enclosing an 'air space for the purposeof heating air, and one or more pipes leading from said air spacethrough the smoke chamber, or through the smoke pipe of the stove, forthe purpose of heating air and conducting heated air into upperapartments for warming purposes, as will be hereinafter described.

To enable others skilled in the art to understand my invention, I willdescribe its construction and operation.

The stove which I have represented in figs. 1, 2, 3, and 4, consists ofa cylindrical body, A, which is secured at top and bottom to cap andbase pieces B and G; the cylindrical portion, A, may be made of sheetiron, and the portions B, C, may bemade of cast iron.

Within this stove issuitably, arranged a cast-ironfire pot or lining, D,which is made with its upper end a flaring. The body or cylindricalportion of this fire pot is of much less diameter than the body, A, ofthe stove, so that a space, I), is formed between the cylinders A and Dinto which air is freely admitted through the perforations cc; the spaceb is closed at its top bythe flange a of the lining D, and at its bottomby the base piece 0, as shown. in fig. 2. thus construct a stove thelower portion of which is adapted for heating air to be conducted out ofthe room, while the upper portion" is adapted for radiating heatdirectly into the room.

E is the opening through which fuel is supplied to the. stove, F is theexit flue or stove pipe,.and G is a heated-air pipe for conducting theheated air from-the space 6, surrounding the fire pot D, into an upperapartment. This pipe G, in figs. 1 and 2, conducts the heated air upwardand through the smoke pipeF, where it receives additional heat from theescaping products of combustion, and from thence the pipe G may becarried 05 or upward to another apartment, where the heated air isallowed to escape,

Instead of leading a pipe from the'chamber 6 outside of the stove, andthence through the smoke pipe as above described, several small pipes,ggg, may lead from this chamber 5, through the/flanged, of the innerwall D, into a drum, J, within the upper portion of the cylinder A, fromwhich the heate air can be conducted by a pipe J whithersoever it may bedesired. In both instances which I have above mentioned it will be seenthat the air which is heated in the,chamber, I), will be re-heated byabsorbing increments of heat from the'escaping products of combustion. Ithus absorb and utilize large quantities of heat which would be'carriedoff up the chimney.

It will be seen that by forming an air-heating chamber around the firepot or lining, D, having inlet openings 'near its bottom, and one ormore outlet openings at or near its top, I obtain afree circulation ofair through this chamber, which will have a tendency to'co ol and keepcool the fire-pot lining D, and to prevent it from rapid destruction byheat, particularly if this lining be made of cast iron.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

, 'The construction of a-stove with an upper, single, heat-radiatingwall, and'with a lower air-heating space, which is formed by the outerwall and fire pot, and which is provided with a pipe leading through thesmoke pipe, or some other portion of the stove where it will be exposedto the escaping-products of combustion as described.
